FIG. 1.

Schematic representation of portions of the ICEPdaSpa1, SXTMO10, and R391 genomes. Conserved genes are shown as gray arrows, and DNA initially identified in ICEPdaSpa1, SXTMO10, or R391 is shown in green, blue, or orange, respectively. The numbered yellow stars represent the sites of hot spots 1 to 4. Note that the scales used to represent the conserved and the nonconserved genes are different and that some conserved genes have been left out of the figure (as have regions without genes). The ICEPdaSpa1 and SXTMO10 insertions in rumB are shown in more detail in Fig. 2. The left border of hot spot 3 in ICEPdaSpa1 begins in the 3′ end of s072, as s073 is absent from this ICE. In R391 and ICEPdaSpa1, s035 is split by insertion sequence elements into two ORFs, noted as s035′ and ′s035. The striped sections in s035 and ′s035 correspond to an ICE-specific variable region.
